Pedigree: In 1968 architect Paul Rudolph transformed a 19th-century carriage house on Manhattan’s Upper East Side into this minimalist haven. The four-story residence, commissioned by a real-estate lawyer, was later sold to fashion designer Halston, who used the living room to host bacchanals for his famous friends. Its most recent owner, the late German-born industrialist and photographer Gunter Sachs, replaced the wall-to-wall carpeting with white-oak floors and added balustrades on the precarious mezzanine and catwalk. The Rudolph scheme otherwise remains intact.

Property Values: Located at 101 East 63rd Street, just off Park Avenue, 101, as the place was called in Halston’s day, has its own garage and rooftop deck.
